A great bakery in Burbank, California (Los Angeles) is Porto's. 

Porto's has been a staple in the city of Glendale for decades but parking there is a nightmare while the newly opened store in Burbank has plenty all the time. I love their sourdough bread loaf (crusty, nutty subtones) while my wife likes their cuban bread, however pretty much anything in the store is great, from breads to cakes and sweets.
